A mezzanine power pin includes a dual layer pin body extending between a pin top having an upper power interface and a pin bottom having a lower power interface. The dual layer pin body has a base metal core and an outer metal oxide layer combined with the base metal core defining an outermost layer of the dual layer pin body. The mezzanine power pin includes an upper fastener coupled to the pin top to mechanically and electrically connect an upper component to the upper power interface. The mezzanine power pin includes a lower fastener coupled to the pin bottom to mechanically and electrically connect a lower component to the lower power interface. The base metal core is configured to electrically connect the upper component and the lower component through the base metal core.
